Netflix and Tesla and Shake Shack Will Lead The Market Higher . . . Because They Are Down

This morning, before the open, Netflix is down another 5%, Tesla down 6%, and Shake Shack 3%.  
Netflix is a great company with a product the consumer is fixated on;  Tesla has captured the imagination of those who can afford the electric car with a range of about 300 miles before you have to plug it in;  Shake Shack has perhaps the best fast food hamburger around.
But all three are overvalued by the measures that investors are taught to look at.  For example, Netflix has a PE ratio of about 250, meaning that investors are paying $250 for $1 of profits.  Apple, by comparison, has a PE ratio of 13.  As the front page soarers come down, perhaps money will flow into blue chip-like stocks again.
Why would these high-flyers be responsible for pulling the market down?  Perhaps because investors have sold more established stocks to get in on The Next Best Thing, thus provoking selling of stocks which should be held.  Money is transient:  when it goes into one thing it comes out of another.
